{'nitrogen gas': [0, 0, 1, 0], 'chemical reaction': [0, 0, 2, 0], 'little chemical reactivity': [0, 0, 1, 0], 'inert atmosphere': [0, 0, 1, 0]}

The correct answer is option 1: Both A and R are individually true, and R is the correct explanation of A.

Nitrogen gas is commonly used to provide an inert atmosphere in chemical reactions. Nitrogen is an ideal choice because it is abundantly available and has a low chemical reactivity at ordinary temperatures. This means that nitrogen does not readily react with other substances, allowing it to maintain a stable environment in the reaction.

The reason provided, which states that nitrogen gas has very little chemical reactivity at ordinary temperature, explains why it is suitable for creating an inert atmosphere. As nitrogen does not easily react with the other substances involved in the reaction, it can help prevent unwanted side reactions or the degradation of sensitive compounds.

In summary, nitrogen gas is used for its inert nature in chemical reactions, and this is because it has low chemical reactivity at normal temperatures, making it a reliable choice to maintain a stable environment.
